Target population included adult patients from the normal patient population seen at Kansas Joint and Spine Institute, currently also known as Kansas Spine Specialists, that have the ability to provide informed consent without assistance. Each patient that is qualified for an anterior lumbar interbody fusion, with an anterior only approach, will be offered the InQu Bone Graft Extender and Substitute as the bone graft the investigator will use in surgery. Patients that proceed with surgical intervention, and that meet all inclusion/exclusion criteria, will be offered enrollment into the study.
